Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"The most valuable features of Cisco firewalls are the IPS and IDS items. We find them very helpful. Those are the biggest things because we have some odd, custom-made products in our environment. What we've found through their IPS and IDS is that their vulnerability engines have caught things that are near-Zero-day items, inside of our network.""The IPS, as well as the malware features, are the two things that we use the most and they're very valuable.""The protection and security features, like URL filtering, the inspection, and the IPS feature, are also very valuable for us. We don't have IT staff at most of the sites so for us it's important to have a robust firewall at those sites""We can easily track unauthorized users and see where traffic is going.""With the FMC and the FirePOWERs, the ability to quickly replace a piece of hardware without having to have a network outage is useful. Also, the ability to replace a piece of equipment and deploy the config that the previous piece of equipment had is pretty useful.""They wanted to leverage something which is equivalent that can give them the next gen features like application awareness and intrusion protection. So that is a major reason they were looking forward to this. The original ASA firewall did not have these features. This was the major reason the customer moved on to Cisco Firepower Threat Defense (FTD). Now they can go ahead and leverage those functionalities.""The Firepower+ISE+AMP for endpoint integration is something that really stands it out with other vendor solutions. They have something called pxGrid and i think it is already endorsed by IETF. This allows all devices on the network to communicate.""Being able to determine our active users vs inactive users has led us to increased productivity through visibility. Also, if an issue was happening with our throughput, then we wouldn't know without research. Now, notifications are more proactively happening."

"The hardware is pretty stable. It's also a very good product performance-wise. Initially, it wasn't mature like a firewall and there were other leaders, but now they have included almost all the features of next-generation security. Basically, it's a good product to work with.""Cisco has always been a premium product. There's a lot of other entry-level solutions. This is more robust.""Completely integrates branch offices with perimeter security.""The capabilities for scalability with this product are huge""Cisco is head-and-shoulders above all of the competition when it comes to technical support.""We are able to filter a lot of traffic especially when a lot of the traffic is in layer 7.""It covers everything we need it to without looking to secondary solutions.""What I have used the most and received the most benefit from is the IPsec technology."

"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use.""The solution is good for a basic firewall for a small business or for home use.""The interface and the dashboard are the most valuable features of this solution.""The most valuable features in OPNsense are reporting and visibility.""The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used.""The most valuable features are reporting, the Sensei plugin, and firewall capabilities.""We have found pretty much all the features of the solution to be valuable.""OPNsense is easy to scale when running on the hardware."

Cons
"The worst part of the entire solution, and this is kind of trivial at times, is that management of the solution is difficult. You manage FireSIGHT through an internet browser. I've had Cisco tell me to manage it through Firefox because that's how they develop it. The problem is, depending on the page you're on, they don't function in the same way. The pages can be very buggy, or you can't resize columns in this one, or you can't do certain things in that one. It causes a headache in managing it.""For the new line of FTDs, the performance could be improved. We sometimes have issues with the 41 series, depending what we activate. If we activate too many intrusion policies, it affects the CPU.""The user interface for the Firepower management console is a little bit different from traditional Cisco management tools. If you look at products we already use, like Cisco Prime or other products that are cloud-based, they have a more modern user interface for managing the products. For Firepower, the user interface is not very user-friendly. It's a little bit confusing sometimes.""We would like to see improvement in recovery. If there is an issue that forces us to do recovery, we have to restart or reboot. In addition, sometimes we have downtime during the maintenance windows. If Cisco could enhance this, so that upgrades would not necessarily require downtime, that would be helpful.""We had an event recently where we had inbound traffic for SIP and we experienced an attack against our SIP endpoint, such that they were able to successfully make calls out... Both CTR, which is gathering data from multiple solutions that the vendor provides, as well as the FMC events connection, did not show any of those connections because there was not a NAT inbound which said either allow it or deny it.""I was just trying to learn how this product actually operates and one thing that I see from internal processing is it does fire-walling and then sends it to the IPS model and any other model that needs to be performed. For example, content checking or filtering will be done in a field processing manner. That is something that causes delays in the network, from a security perspective. That is something that can be improved upon. Palo Alto already has implemented this as a pilot passed processing. So they put the same stream of data across multiple modules at the same time and see if it is giving a positive result by using an XR function. So, something similar can be done in the Cisco Firepower. Instead of single processing or in a sequential manner, they can do something similar to pile processing. Internal function that is something that they can improve upon.""The product line does not address the SMB market as it is supposed to do. Cisco already has an on-premises sandbox solution.""The central management tool is not comfortable to use. You need to have a specific skill set. This is an important improvement for management because I would like to log into Firepower, see the dashboard, and generate a real-time report, then I question my team."

"I would love it if it has a link-by-link feature, integration with Unified Threat Management (UTM), and load balancers. They haven't got any link-by-link feature right now, which can be a very attractive option. This link-by-link feature can also be made available for Cisco's UTM firewalls. The link-by-link feature is available in some of the other firewalls. Currently, integration with UTM is missing. Cisco IOS Security also doesn't have the load balancers and a few things that need to be done to get a good UTM firewall. Normally, other firewalls have UTM. As a next-generation firewall, it's good, but as a UTM, it has to do some work.""The company needs to make its solution more affordable to make it more accessible to larger markets. Otherwise, it's seen as an enterprise-level solution that small or medium-sized organizations can't afford and therefore they won't even look at it.""The pricing is the only con for this product.""The user interface needs to be improved.""Signatures and other critical definitions need to be updated more frequently.""With respect to user-friendliness, it is a command-line interface and those with such experience will get along just fine, whereas others may struggle.""It would be ideal if the solution had more capacity.""The configuration should be easier in the solution."

More Cisco IOS Security Cons »

"The ability to set the VPN IP address would be a welcome addition.""The solution would not be suitable for anything large-scale.""There should be more technical documentation.""There are issues with stability and reliability.""The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform.""I would like to see better SD-WAN performance.""The solution could be more secure.""The interface needs to be simplified. It is not user-friendly."

Pricing and Cost Advice
"Our subscription costs, just for the firewalls, is between $400,000 and $500,000 a year.""Cisco's pricing is high, at times, for what they provide.""The one-time cost is affordable, but the maintenance cost and the Smart Net costs need to be reduced. They're too high.""We normally license on a yearly basis. The hardware procurement cost should be considered. If you're virtual maybe that cost is eradicated and just the licensing cost is applied. If you have hardware the cost must be covered by you. All the shipping charges will be paid by you also. I don't thing there are any other hidden charges though.""Cisco pricing is premium. However, they gave us a 50 to 60 percent discount.""There are additional implementation and validation costs.""Cisco, as we all know, is expensive, but for the money you are paying, you know that you are also getting top-notch documentation as well as support if needed.""This product requires licenses for advanced features including Snort, IPS, and malware detection."

More Cisco Firepower NGFW Firewall Pricing and Cost Advice »

"It is an expensive solution.""The pricing is okay. It is competitive. It costs more when you need get more features.""Price is certainly something that the IOS technology has fallen behind the competition on.""It is necessary to pay for a license in order to use the solution. It is on a yearly basis and the price is high.""Palo Alto networks are more expensive than this solution and this is why you will see more products like this one in Mexico.""The price of the solution should be cheaper, and the license is purchase annually."

More Cisco IOS Security Pricing and Cost Advice »

"OPNsense is open source software so at this time it is free for us to use.""OPNsense is a well known open-source tool.""It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source.""OPNsense is an open-source solution and it is free to use.""The solution is not expensive.""As an appliance, it's in the medium price range."
